AUTOMOBILE-LOCK.

characters on the drawing representing like parts.

My invention has reference to locking devices by which a controlling lever may be locked in one position and is particularly adapted to be applied to automobiles for holding a controlling lever in neutral or inoperative position.

One object is to provide a locking device that may be readily applied to existing automobiles.

Another object is to provide a locking device which when applied to an automobile may be placed on the machine in such a position that it can be conveniently reached from the seat, and which need not be in any way connected to the H gate or other lever guiding devices.

Other objects will appear from the following specification in which my invention will be fully disclosed and the novel features will be particularly pointed out in the claims.

In the drawing: Figure l is a view partly in section of my improved device; Fig. 2 is a plan view'of the same; Fig. 3 is a sectional view on the line 33 Fig. 1 g and Fig. 4 is a view on the line H Fig. 1.

Referring to the drawing which illustrates one embodiment of my invention 1 indicates controlling lever of an automobile to which my'device is applied and 2 in dicates a part of the frame to which the lock-case 3 is permanently secured.

, A,movable arm t is preferably pivotally connected to-the lever 1 as by means of a strap 5 and rivet 6. so that it may swing up to locking position as shown in full lines in Fig. 1 or down to inoperative position as shown in dotted lines. The keeper 7 is shaped to receive and interlock with the movable arm 4. l haveshown this keeper as made integral with the lock-case but it is sometimes desirabl to make it as a-sep-- aratc member. in the constriction shown. in the drawing the arm 4- is provided. with which tits in a corresponding rea. tongue cess 9 in hc keeper 7 and a rio it) formed in Specification of Letters LPatent.

the keeper fits in a transverse recess .11 in the tongue 8. Thus when the parts are. in interlocking posit-ion as shown in full lines in Fig. l, movement of the arm in a longitudinal direction is prevented by the engagement of the rib 10 in the recess 11.

To lock the tongue 8 in the recess 9 of the keepe and thereby prevent movement of.

the arm in a downward direction, I provide a locking member 12 having a spring pressed locking pin 13 in its forward end, the forward movement of this pin being limited by a shoulder as shown at 14. A recess 15 is provided preferablv in the end of the tongue 8 to receive the pin 13 and the tongue is beveled to press the pin back into the lockingmember as it moves into the recess inthe keeper. The locking member 12 is slidable in the keeper and may be controlled by any suitable mechanism. In the construction shown a tension'spring 16 is secured to the locking member 12 and to the opposite side of the lockcase. An upwardly extending arm 17 on the locking member is engaged I'JV two rotatable disks 18 and 19 and thereby held in forward position against the action pf the spring. The lower disk 18 is secured to the stem 20 and is provided with a pin 21 which is adapted to engage-a pin 22 in the disk 19 which latter disk is rotatably supported within the lock-casein any suitablemanner. The head of the stem 20 is knurled as shown at 23 and a scale is provided as indicated at 24 as is usual in combination locks. The disk 18 is provided-with a notch clearly shown in Fig. 4, one side of the notch being shaped as a cam to force the locking member into its forward position. The other disk 19 is provided with a notch 26 as shown in dotted lines in F at. -As will be seen. thestem 20may be rotated in one direction the pin 21 engaging the pin 22 and thereby rotating the disk .19 until the notch 26 is opposite the arm 17 of the locking member. Then the stern may be rotated in the opposite direction imtil the notch of the disk 18 is in a position onposite. the arm 17 i and the spring 16 will operate to draw the locking member backwari'l releasing the movable member i.

I prefer to provide means to hold the movable arm in iis operative posi" 1 in its inoperative position relative er and in the en'ilmdiment of my n illustrated I have accordingly d a yieldof the locking member The operation of the device is as follows:

- When it is desired to apply the lock the from said arm and comprising a lever is moved to the position in which it is adapted to be locked and the movable arm 4; is raised to engage the keeper 7. The locking pin 13 is pressed backwardly against its spring by the beveled end face of the arm until the recess in the end of the arm comes opposite the -locking pin whereupon the pin springs into said recess. When it is desired to unlock the lever the disks are rotated by means of the stem 20 as above explained, to bring both notches opposite the upwardly extending arm 17 of the locking member andthe locking member is Withdrawn by the spring 10. Thearm 4% may down and the lever is free to The stem may then be turned to force the locking member into its forward position and the parts are in position to be readily locked again, when desired.

Having: described my invention, What 1 claim as new and desire to secure by Letters Patent is z- 1. A device of the class described comprising a movable arm, a keeper shaped to receive said arm and a locking member movable relative to said keeper toward an body member and a. springpressed locking pin carried by said locking member-and yieldable relative thereto to permit the insertion otthe arm in the keeper b at normally positioned to retain said arm when inserted.

2. A locking device eon'iprising a keeper, an arm movable to engage the keeper and interlock therewith in such a manner as to then be pushed be operated l l l l prevent relative movement in one direction, a lockingmember movable relative to the keeper and comprising a body member and a spring-pressed locking pin movable relative to said body member to engage the movable arm and retain it in interlocking engagement with the keeper and means for controlling the locking member.

3. A device of the. class described comprising an arm adapted to be connected to a lever, a keeper shaped toreceive the arm, a locking member movable relative to said keeper and toward and from said arm when said arm is in position in said keeper, and comprising a body member and a springpressed locking pin carried by said body member yieldable to permit insertion of the arm in the keeper WllllC the body member is inposition toward said arm, but positioned to retain said arnrivhen inserted, and means controlling; said, locking: member.

4, A device of the class described com: prising an arm adapted to be p ivotally connected to a lever in siich. a manner that it is capable of movement to operative and inoperative p0sitions,.a keeper shaped to receive said arm and interlock therewith to prevent longitudinal or lateral movement 0' said arm, means to lock said arm in said keepercomprisine a slidable member and a spring-pressed pi-n'earried by said slidable member and movable relative thereto.

In testimony whereof, I havesigned my nan'ie to this specification, in thepresence of two subscribing Witnesses.
